A Taste of the Past in a Flash!The Flashpoint FlashBack Senior Speedflash is the miniaturized blend of the original popular on-camera Automatic Speedlight, introduced way back in 1972, and the reflector flash design of the 1930s. The Flashpoint FlashBack Senior Speedflash single-pin hot shoe trigger assures compatibility with camera with a hot shoe or a sync post for triggering.Less ThanbRGreater ThanNot just the traditional list of popular current craze cameras, but cameras with a live hot shoe or a really old-school sync post. Since the automation is f-stop related on the flash body - through a sensor on the flash body, not TTL camera linked - once the lens is set to the suggested displayed f-stop, the exposure comes out accurate and rich. Camera platform examples: Canon, Nikon, Sony, Fujifilm, Panasonic, Olympus, or Pentax - Exacta, Contax, Leica, Konica, Linhof, and more.The simple fact that is an undeniable advantage of the FlashBack Senior Speedflash is the price vs. performance data. The guide number is designed for convenience, not superpower performance. The ease of rechargeable lithium-ion cells as the built-in power solution for battery freedom assures dependable, uninterrupted flash photography is marvelous.Remember the Fan?The retro fan shape that opens and closes in a circular 9-blade silver dish is reminiscent of the days when reflectors ruled. The delicate flashbulbs were centered in the holder of the reflector bowl. Every shot counted.
